Background Art

Machine tools refer to machines used to manufacture machines, also known as machine tools or machine tools, and are usually referred to as machine tools. They are generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools. There are many methods for processing mechanical parts in modern machinery manufacturing: in addition to cutting, there are casting, forging, welding, stamping, extrusion, etc. However, all parts with high precision requirements and fine surface roughness requirements generally need to be finally processed on machine tools by cutting methods. Machine tools play a major role in the construction of national economic modernization. According to processing needs, machine tools are divided into hydraulic punching machine tools and hydraulic stamping machine tools. Hydraulic punching machine tools are a kind of machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to realize various processes. The hydraulic press is generally composed of three parts: the machine, the power system, and the hydraulic control system. The hydraulic punching machine is suitable for punching operations of various steel, iron, copper, aluminum plates, formed steel, channel steel, I-beams, etc. It is small in size, light in weight, easy to operate, labor-saving and fast in punching.

Existing hydraulic punching machines need to fix parts before punching, but the fixing method mostly adopts manual fixing, which makes the degree of automation low. In addition, the fixing fixtures used in existing hydraulic punching machines are mostly not convenient to adjust according to the size of parts, and have great limitations in use and cannot meet production needs. Therefore, a hydraulic punching machine is proposed to solve the above problems.
